A tree is a well-known data structure that is either empty (null, void, nothing) or is a set of one or more nodes connected by directed edges between nodes satisfying the following properties.
1) In cases where there is no match to any of the patterns
mentioned in the problem description DON'T print a blank line
2) Dont' print eoln at the end of output
Thanks for your answers. I've finally solve this problem. I've created two arrays: bool wasadd[2 000 001] and int sums[2 000 001] It's "only" ;) 2 000 000 possible sums. I show my algorithm using example: Set: 2,3,4 Sum to find: 7 wassadd[2+1 000 000] = 1; sums[0] = 2; for members of set from 3 to 4...
There is a set of N integers in range [-1000, 1000], N< 1000 I have to find if there is any subset which sum of elements is exactly S. S is an integer in range [-1 000 000, 1 000 000 ] Example: Set - {5, 10, 25, 50} S = 30 I can find a subset {5,25} - 5+25 = 30 Set - { -6,9,100,-45} S = -42 I can fi...
I had this problem too.
1. C(n,k) = C(n,n-k)
2. My program memorizes C(n,k) for n and k < 1000
3. C(n,0) = 1;
C(n, n) = 1;
C(n,1) = n;
I hope it will help you.
